TI中文支持网由于硬件的原因不能使用ROM中的bootloader实现升级，自己通过uart1实现 了一个boot,能正常更新flash，但是，当在boot中使用过中断后，例如串口中断、定时器中断，调用跳转函数jumpToPrgEntry(0);不能正确跳转到app区，会死机，已确定app区的flash正确。现猜测是中断向量表的问题。代码中有两个向量表，一个是falsh区的readonly section .intvec，一个是ram区的section .vtable_ram。请问app和boot中中断向量表需要如何设置

感谢你的回复，看了那个帖子了，并没有给出解决办法，在bootloader的icf中有分配ccfg区域，我的bootloader放在flash的最后几页，app放在flash的0x00位置
bootloader中配置，#define SET_CCFG_IMAGE_VALID_CONF_IMAGE_VALID 0x50000
